FURNACE caanunn'roaz Application filed January 20, 192-6. Serial No. 82,591.

:: Thisiinvention is designed for use in the fire-pot of a furnace, and it resides in a skeletondevice which may readily be installed in existing furnaces without dismantling the 5 same. Itspurposeis to promote and increase combustion by admitting heated air to the combustion chamber, whereby a more complete consumption of the gases generated I in the distillation of the fuel is effected.

The device consists of a series of castings formed so as to permit their disposition about the interior of and in contact with the fire-pot lining, each casting being formed as a vertical body provided with a longitudinal air conducting channel, and with laterally extending arms or spacers designed tocontact with like arms or spa'cers upon adjacent bodies, the assemblybeing such as to completely encircle the fire-pot. The arms are adapted to be connected to each other. so that when the assembly is completed, a circular structure is produced, with its parts maintained in positionat all times and effectively guarded against displacement.

The spaced arrangement of the sections which is preserved by the provisions of the arms and their engagement in the manner described, will permit a larger proportion of the fuel undergoing consumption to bear directly against the walls of the fire-pot, thereby causing a more direct radiation of the heat, with improved results, especially in connection with hot water systems.

The details of my invention will now be particularly described, and the novelty there of will be pointed out in the appended claims. In the accompanying drawing:

Figure 1 is a vertical sectional view of a conventional heating furnace, showing my invention as applied thereto, the view being taken on the line 1-1, Fig. 2.

2 is a horizontal sectional view through the furnace, taken on the line 22, Fig. 1.

Fig. 3 is a view in elevation, somewhat perspective, showing the formation of one of the elements of my invention.

In the drawing, the numeral 10 indicates the fire-pot of a conventional furnace, the fire-pot resting upon the base 11 and being surmounted by the dome 12. A grate of suitable construction will be provided at the bottom of the fire-pot.

The improved carburetor is made up of a succession of devices having the form illustrated in Fig. 3, each such device being formedlas a vertical body15having later- I ally extendedarms 16 near. its upper end and like arms 17 near its lower end. The arms 16 and 17 are slightly curved as shown in Fig. 2, so as to conform to the curvature of theinside of the fire-pot, the radius of the curve being determined by the diameter of thefire-pot. The arms .16 and 17'are faced upon radial lines, and their ends are provided with openings 18 forthe reception of pins or dowels 19, by means of which the circular arrangement of the. assembly is preserved concentrically of the fire-pot. The number of elements 15yemployed in building up the circular assembly shown in Figs. 1

and 2, will be determined by dividing the width overall of one into'the circumference of the whole. The usual taper existing in fire-pots will permit an easy assembly of the circular structure, which is then lowered until it is brought into position at the bottom of the fire-pot.

The laterally extending arms or spacers 16 and 17 separate the bodies 15 to an extent which will expose considerable areas to the action of the heat, and so increase the efficiency of the furnace. 1

Eachof the bodies 15 is provided with a vertical channel 20, which preferably is formed in the casting at; the time of making the same. The lower end of the casting is cut away as at 21, so as to permit free ingress of currents of air into the channels. These currents of air pass upwardly through the channels and discharge into the ,combus .tion chamber of the furnace,produci'ng a much higher consumption of the gases generated inthe fire-box. y

In general form, the parts 15 are wider at-their lower ends than at their upper ends, and the channels are correspondingly formed, there being a constriction of the latter at the said upper ends. This particular feature of construction will obviate clogging of the channels, and will permit the freedischarge of ashes or clinkers which may seek lodgment therein. 1

Having thus described my invention, What I claim and desire to secure by Letters Patent of the United States, is: 1. Ina furnace, the combination ofa firepot and a carburetor therein, the said car- .buretor being composed of aplurality of like parts arranged interiorly about the firepot, and provided with channels for conducting air to the combustion-chamber, the said parts being also provided with lateral arms which space the said parts in the arrangement described.

2. In a furnace, the combination of a firepot and a carburetor arranged interiorly of the same, the said carburetor comprising a plurality of parts oined in circular arrangement but spaced apart to expose areas of the fire-pot lining directly to the fuel, the

said parts being provided also with vertical channels for leading air to the combustion chamber.

In a furnace, the combination ot a firepot and a carburetor therein; the said caring it from adjacent parts, and provided also with a vertical channel for conducting air to the combustion chamber.

4;. In a furnace, the combination of a tirepot and a carburetor therein, the said carburetor being composed of a plurality of body sections provided With vertical channels for the upward movement of air into the combustion chamber, said body sections having oppositely extending arms Which space the body sections circularly of the firep'ot, and means for connecting the said arms at their meeting ends.

In testimony whereof, I have signed my name at Milwaukee, this 6th day of Janua-ry 1926.
